Uber's presence in Africa has undergone significant changes. The company introduced a cash experiment, allowing riders to pay drivers in local currency, which eventually became a standard feature globally. This innovation was first tested in Nairobi, then in other cities.

The company's operations in Africa have since been scaled back. Uber shut down operations in two countries without notice. Prior to this, the company had exited other markets in the region.

Further details on Uber's operations and changes in Africa are available from the source, including the current number of African markets where the company still operates.
